MOLDING AND GROOVING HEAD.

To all whom it may concern:

Be it known that I, WVILLIAM J. MoSon- LE1, citizen of the UnitedStates, residing at Eau Claire, in the county of Eau Claire and State ofWisconsin, have invented certain new and useful Improvements in Moldingand Grooving Heads, of which the following is a specification.

This invention has relation to heads for matching, molding and groovingmachines, and has for its object to provide a head of simple structureupon which may be located cutting blades of any desired configurationand which may be adjusted to any desired position. The head is alsoprovided at its opposite sides with concaved channels with. boltstraversing the lengths thereof. Grooving saws of peculiar configurationare pivotally mounted upon the said bolts and bear at their edgesagainst the bottoms of the said channels, whereby they are braced-inpositions against their work.

In the accompanying drawing: Figure 1 is a perspective view of the head;Fig. 2 is a sectional view thereof cut transversely across its axis; andFig. 3 is a sectional view thereof cut longitudinally of its axis.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingby the same reference characters.

The head 1 is provided with a central opening in which is located ashaft 2. Any suitable means may be provided, as for instance a set screw3, for securing the head 1 to the shaft 2. The head 1 is provided at itsopposite sides with channels 4- which terminate short of the ends of thehead. These channels are provided with concaved bottoms 5. Bolts 6 aresecured at their ends in slots 6 provided in the end portions of thehead 1 and traverse the lengths of the channels 4. The said bolts arespaced from the concaved bottoms 5 and are approximately in concentricposition with relation thereto. Nuts 7 are screw threaded upon the bolts6 and lie between the ends of the Specification of Letters Patent.

length so that the inner edge portions of.

the blades 9 may bear in close contact against the concaved bottoms 5 ofthe channels 4. The blades 9 are provided at their outer edges withteeth 11 which are ar ranged concentric with relation to the axis of theshaft 2.

The head 1 is provided at its opposite sides and at points approximatelymidway between the channels 1 with grooves 12 which extend from end toend of the said head. Bolts 13 are adjustably secured in the saidgrooves and nuts 14 are screw threaded upon the outer ends of the saidbolts 13. Blades 15 are adapted. to lie flat against the opposite sidesof the head 1 and are provided with elongated slots 16 which receive thebolts 13, and the nuts 14: are adapted to be screwed down against theouter faces of the last mentioned blades and clamp the same in adjustedpositions against the opposite sides of the head 1.

The cutting edges of the blades 15 lie imme' diately behind the sets ofteeth 11 carried by the saw blades 9 and the cutting edges of the blades15 may be of any desired configuration.

In operation the blades 15 are designed to form surfaces upon the edgesof a strip of wood, while the said blades 9 are designed to groove ortongue the same. These blades may be adjusted to cut deep or shallow asdesired.

Having ,thus described the invention, what is claimed as new is:

A head having at its side a channel which is bounded at its ends by theend portions of the head, a bolt traversing the length of the channel,the ends ofthe head having elongated slots which receive the ends of thebolt, means for securing the bolt clamping said blades in position uponthe in an adjusted position in the slot, clamping bolt. 10 nuts locatedWithin the channel upon the In testimony whereof I affix mysignaintermediate portion of the bolt, and blades ture in presence oftwo Witnesses.

having at their inner portions slots which WVILLIAM J. MGSORLEY. [11. s]open at their ends at the edges of the blades, Witnesses:

said slots in the blades receiving the inter- J. W. SCOTT,

mediate portion of the bolt and the nuts B. F. HEADLEY.
